Triumph TR6 - Fuel Treatment-Storage

Has anyone heard that use of fuel treatment such as STABIL should be avoided. I have been using this when storing my TR winters for almost 10 years with no problems. Apparently, this additive will wear out fuel lines, hoses, etc. I have heard that it is better to use a fuel additive normally used with marine motor applications. Anyone else hewar this?


Probably no worse than the stuff in our gas.
I use the marine stuff

I have used it for many years Shawn in mowers, outboards, and cars (including my TR6) with no issues. Having said that I should say that I switched to Mercury Marine Fuel System Cleaner/Stabilizer for my four-stroke outboard due to too few hours of use causing gummed up carbs (4). It was recommended by my marina so I went with it instead of Stabil. I still use Stabil in the Six.

Hi everyone,

Time of the year to store our babies...I have for several years managed to do the oil change and filter replacements before I store the car. Should I do this in the late Fall before I store it or in Spring.

Thanks for your feedback !

I have never used stabilizer for my cars. I stored my Spitfire every winter for 30 years and have never had a problem My TR6 has gone 5 years now and I haven't had any need to reset the carbs or had any problem. Now my lawnmower is a different story. I get gum build up in the float bowl if I don't use it.


I do my oil change in the spring but you will probably find an even split in opinion for either option.

Hi Guys
As I understand it when "used" oil sits for a few months it becomes acidic and may slightly etch the metal, fresh oil stored in the engine takes a lot longer to do that so that's why it's recommended for all motors to drain dirty oil and store with clean oil. As for the gas tank I fill mine ( reduces condensation in tank) and add some fuel stabilizer.
Before I park mine I change the oil, add some Lucas stabilizer..go for a good run to mix it all up and park it...never had any problems.

Thanks all: I basically do the same. I had heard recently that because of what is being added to fuel these days that it was a good idea if you used any stabalizer it should be the marine type.
